I am taken from the world to give judgment.
I could be the devil with the power of the fool.
Together with the traitor we are death;
A difference to he and she who rule.
Before the sign of the unknown,
Mine own in front of the old man is found.
As you see, to some I am I,
But to others I am he who will confound.

Who or what am I?

I'm guessing -gold. Hope its okay to post the answers, 'cause I couldn't find a place other then this to submit my guess.
